Is there a valve that you could manually operate to adjust the flow of coolant?

And by constant he means, you can literally set the suction pressure, depending on the rating of the valve, and it will keep it there.

Yep yep, you'll want a low side pressure gauge on any system with a CPEV.

I was searching for CPEV's and I found this. It gives a pretty basic explaination of different metering devices.
